It may be about USA life, but this from Cafe Hayek crosses the pond very nicely:
Here's a letter that I sent today to the Wall Street Journal:
David Perel offers good reasons why today "Everything About Politicians Is Fair Game" (September 11, 2008).
But Mr. Perel overlooks what is surely the fundamental reason: tit-for-tat. Because everything about private citizens has become fair game for politicians - everything from our retirement planning to what we ingest and even to the sizes of our toilet tanks - it is not surprising that citizens eagerly pry into the intimate lives of politicians.
Those who raise busy-bodyness into a chief motive-force of public policy can hardly complain when their officious Frankenstein monster turns on them.
